About the role:
As IT Manager, you will be responsible for Lengow’s internal IT environment, supporting 150 employees across Nantes, Paris and Barcelona.
Reporting directly to the CTO, you will work in a two-person IT team: you and an IT apprentice (Systems & Networks Technician).
This is a hands-on role: you will manage day-to-day IT operations and user support, while also working on IT projects, migrations and improvements. You will work autonomously across a broad IT scope, support the apprentice and coordinate external IT providers when needed.
You will also have the opportunity to improve our tools, infrastructure and processes, and contribute to the IT roadmap with the CTO.
Your main responsabilities:
🛠️ IT operations and user support

- Support and guide the IT apprentice in daily operations.
🔑 Identity, endpoint and asset management
- Administer Google Workspace, Active Directory and the main corporate SaaS applications.
- Manage the complete lifecycle of user accounts, including groups, roles and permissions.
- Maintain and improve SSO, MFA and role-based access management.
- Manage endpoint configuration, patching, encryption, antivirus and device compliance.
- Manage the lifecycle and inventory of laptops, mobile devices and IT equipment.
- Prepare and improve employee onboarding and offboarding workflows.
🌐 Network and infrastructure
- Operate and maintain the internal network infrastructure across the Nantes, Paris and Barcelona offices.
- Administer network infrastructure including switching, routing, Wi-Fi, VLANs, firewalls and access-control systems.
- Operate Lengow’s internal infrastructure hosted primarily on Google Cloud Platform.
- Administer Active Directory, DNS, DHCP and LDAP/LDAPS and related identity services.
- Maintain secure remote access and connectivity between users, offices and cloud environments.
- Troubleshoot network, system and connectivity incidents.
🔐 Security and compliance
- Maintain endpoint security, patching, encryption and vulnerability-remediation processes.
- Monitor the security status and compliance of employee devices.
- Support the response to internal security incidents and remediation plans.
- Maintain security procedures and participate in continuity and recovery tests.
- Contribute to customer security questionnaires, audits and due-diligence requests.
🚀 SaaS, vendors and projects
- Administer and maintain Lengow’s portfolio of internal SaaS applications.
- Manage IT contracts, licences, renewals and supplier relationships.
- Negotiate with vendors and challenge technical and commercial proposals.
- Monitor IT spend and identify opportunities to simplify the toolset and reduce recurring costs.
- Lead Corporate IT projects and continue the modernisation and standardisation of Lengow’s IT environment.
- Improve processes and automation, maintain documentation and build the Corporate IT roadmap with the CTO.
